Crystal radio technology has been around for many years. This "bottle radio" take on a crystal radio requires no power source, operates on the power from radio waves, and receives signal from a long wire antenna. As radio stations slowly move away from the AM band, the "window of opportunity" to experience this remarkable technology is dwindling. The "crystal" in question is contained inside a germanium diode, and is used to rectify the radio signal so that our ears can hear it.
My grandpa did one in Poland during WWII to listen to London Radio. It was extremely dangerous: if Germans had found the radio, he would have been killed in place.
You guys did this one already. It's how I found the channel.
Very clear instruction! Now I just have to find the time to make it. Thanks.
Note: A lot of coat hangers are coated in varnish/enamel of some sort. You may need to sand it off where it contacts the screw,and the coil.
I didn't think that crystal ear phone was still around, the first radio I made was a foxhole radio 55 years ago
This was a really well done video. Do more like this.
You guys could start a new world if one ends.
This is what Make should be about.
Wow I can't believe it's that simple I'll make this one day it uses everything that is easy to find!
I built one of those before but it came in a kit that I bought from radio shack. It actually worked to even though my dad told me it can be hard to get these things to work on the first try.
Woo amateur radio enthusiasts!! I've always loved simple foxhole/cats-whisker's radios, it's amazing how they work.
Great video! Thank you Weekend Projects.
That was awesome, can't wait to try it out. Thanks.
I'll sure try this one. Thanks.
I was making such radios in my childhood.. eh.. there was a time.. :)
Very nice build.
VERY cool project!
Thank You! This is a great project.
finally! something within my relative price range!
that radioshack mini amp is great for making dyi ipod speakers, only issue is the speaker in it is crap and gets impossible to hear after you turn the volume just a little bit
i've wanted to do this for years...thanks....
You guys made this a little costly. We use to use parts and wire scrounged from old electronics and a oatmeal box (also known as a mush box) instead of a bottle. It would be cheaper to by a store bought kit then buy the materials for yours.
This is really cool!
REALLY nice!
but it would be even more awesome if you would have explained the physical/electrical processes behind it, cause those are genius! (I know them and I was really amazed^^)
great project
Can it be made smaller?
as long as there is a radio shack
Well done yous!
Not a water pipe but w/e. Is there a reason you don't use the crimps on those pliers?
I love these! I remember as kid on the bps show "zoom" where they had a demo of one made with two tin cans that fit indie of each other. you would rotate the tow cylinders to change station. I would love to see that on here? Anyone? :) Thanks!
Chris
you guys have already done this project
i love make!
you guys rock
I'm sure you might get questioned by security if you brought this anywhere near an airport.
can you tell me how to waterproof a normal battery powerd radio/CD player?
Now that's what i call spin the bottle
amazing!
Awesome!!!
muito legal,ao contrário do que pensam nós brasileiros, tanto estudamos quanto gostamos muito de tecnologia.
pretty cool
please the software used for montage :)
cool radio
So basically it's like the foxhole radio you uploaded WAAAYYY back when...dam...I remember that hitting my subscribers box and not list!
I thought the bottle would be used in place of a speaker but then I saw that it was a crystal radio.
cool video now i have to make it :)
You rock
this was actually pretty cool, and WHY THE HELL are you holding my comment for approval?
So you're not going to actually demonstrate it?
Great!
I was expecting "...and instead operates only on the power of WIZARDRY!!!"
which one?
Stuff like this is why I'll survive the zombie Apocalypse. lol
Great video, can't wait to try it!
Cool!
So you know, saying 'You will also need' and then just showing the materials and their names feels awkward. next time, just read them off quickly and let the image sit for a second after you are done reading. Otherwise, very cool video!
woow nice video :D
Awsome
i wanna make 1
Cool, I think.
This is pretty fucking cool!
Camera! Shaking! ARRRGGGG!!! Good video though! :D
nice
Budweiser Bottle Radio for kids
I thought I would do this, but I wont!
Cool
cool me gusto bien :)
It looks like so called "fox hole" radio. Too bad it only uses AM (amplitude modulation), cause FM is the fácto in my state.
Listens to am
this is really cool.... just saying
this will be great for when the zombie Apocalypse comes
um cool!
Y not just buy cheap radio and much cheaper... And who liste
to bad it is not a fm radio
no no no no no no no no.NO......they need to bring kip kay back.
BRE PETTIS did it better

Well done yous!
